DETAILED DESCRIPTION OF THE INVENTION

The present invention will now be described in detail with reference to embodiments thereof as illustrated in the accompanying drawings, in which like reference numerals are used to indicate identical or functionally similar elements. References to “one embodiment”, “an embodiment”, “an example embodiment”, etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

The following examples are illustrative, but not limiting, of the present invention. Other suitable modifications and adaptations of the variety of conditions and parameters normally encountered in the field, and which would be apparent to those skilled in the art, are within the spirit and scope of the invention.

Embodiments of the present invention include a system 10 for monitoring the location of one or more individuals during a fitness activity. In various embodiments, the present invention includes a system 10 for monitoring the location of a participant (e.g., an athlete) 100 in a fitness activity and the location of a spectator 200 of a fitness activity. The spectator may include a coach, trainer, parent, supervisor, fan, aid station attendant, doctor, or other spectator of the fitness activity. In one embodiment, another participant may be a “spectator” as they may wish to track the performance of the participant 100. It will be understood that a spectator may not be physically viewing the participant or the race. During the fitness activity, the system 10 may send an alert to the spectator indicating that the participant is within a predetermined distance or time of reaching the spectator. During the fitness activity, the system may also send an alert to the participant 100 that the spectator 200 is within a predetermined distance or time of the participant. In this manner, embodiments of the present invention may provide real-time location awareness of the participant and/or spectator, and provide an enhanced participation or spectating experience of the fitness activity for individuals involved. For example, having been alerted that the participant they are tracking is approaching, an interested spectator may be informed to look for the participant and be ready to cheer on that individual or provide services (e.g., aid, water, equipment, etc.). Similarly, having been alerted that a spectator connected to the participant is approaching, a participant may be motivated or encouraged to perform during the fitness activity. Embodiments in which location alerts are provided to both the fitness activity participant 100 and the spectator 200 may increase the likelihood of the individuals being able to interact during the fitness activity.

With reference to FIG. 1, the system 10 includes a portable fitness monitoring device 102 used by a fitness activity participant 100 and adapted to determine and/or transmit the location of the participant during the fitness activity. The portable fitness monitoring device 102 is in communication with a fitness activity server 112 over a network 110 and may communicate the location of the participant 100 to the server 112. The system 10 further includes a spectator device 202 adapted to determine and/or transmit the location of the spectator 200 during the fitness activity. In one embodiment, the spectator device 202 is in communication with the fitness activity server 112 and/or the portable fitness monitoring device 102 over the network 110 and may communicate the location of the spectator 200 to the server 112 and/or the device 102.

In one embodiment, the portable fitness monitoring device 102 transmits an alert regarding the location of the participant 100 to the spectator device 202 directly, and the spectator device 202 transmits an alert regarding the location of the spectator 200 directly to the portable fitness monitoring device 102. In another embodiment, the server 112 transmits the alerts to the respective devices.

As will be appreciated by one of ordinary skill in the art, one or both of the portable fitness monitoring device 102 and the spectator device 202 include one or more processors adapted to implement application programs that provide the fitness monitoring methods described herein. In one embodiment, the fitness monitoring methods may be accessed and operated as a mobile application or “app” for a smartphone. For example, a fitness activity “Live Tracking” application may be downloaded to the portable fitness monitoring device 102 and the spectator device 202 from server 112 or a known smartphone application market. In some embodiments, a fitness activity “Live Tracking” application may be incorporated within another application, such as, for example, a fitness monitoring application.

As will be appreciated, a user may operate the “Live Tracking” application by selecting, for example, an icon on the portable fitness monitoring device 102 or the spectator device 202. For example, the user's touch or a touch gesture on the icon may initiate the application. The computer readable media for executing the application may be stored on the server 112 or in memory on the devices themselves, or combinations thereof. In other embodiments, the user may access a web site provided by the server 112 to provide a portion or all of the fitness monitoring methods described herein. The version of the website accessible from the portable fitness monitoring device 102 and/or spectator device 202 may be simplified or otherwise modified to optimize it for display on a relatively small screen, such as, for example, the display of a smartphone or tablet computer.

The server 112 may be, for example, a telecommunication server, a web server, or other similar types of database servers. In an embodiment, server 112 may have multiple processors and multiple shared or separate memory components such as, for example, one or more computing devices incorporated in a clustered computing environment or server farm. The computing process performed by the clustered computing environment, or server farm, can be carried out across multiple processors located at the same or different locations. In an embodiment, server 112 can be implemented on a single computing device. In one embodiment, as shown in FIG. 1, the server 112 may include or be in communication with a fitness database 113 that may include an account of the participant 100 and/or spectator 200, a route database having stored route information, a training journal database having real-time or historical performance information regarding the workouts, performance and training of the participant 100, and/or a training plan database having a schedule of fitness activities scheduled for the participant 100 and/or spectator 200. For example, the fitness database 113 may include data storage according to embodiments described in U.S. Publication No. 2011/0082641, entitled “Methods and Computer Program Products for Providing Information About a User During a Physical Activity.” The server 112 and/or fitness database 113 may include or provide access to a fitness website that provides access to an individual's account information and data. The website may provide an interface for performance data analysis and review, training scheduling, and other functionality regarding participant and/or spectator performance monitoring. Other individuals who have access to or accounts with the fitness website may define an athlete community in which participants and spectators may interact. The server 112 may also include or be in communication with a social network database 114 related to the participant 100 and/or spectator 200, as discussed below.

The fitness activity may include any fitness activity engaged in by the participant 100 and viewed or attended by the spectator 200. In one embodiment, the fitness activity is a competitive fitness activity, including, but not limited to, a foot race, a bicycle race, a skiing or snowboarding race, or other fitness activity in which the physical location of the participant 100 changes as a function of time. For example, the fitness activity may comprise an organized competitive running race such as the New York City Marathon, the Army Ten Miler in Washington, D.C., or a high school cross-country race. In an embodiment, the fitness activity may be a self-organized activity. For example, a participant may organize a fitness activity to be engaged in with one or more individuals, such as family, friends, or members of a social network or fitness community.

In one embodiment, the fitness activity includes a predetermined route to be traversed by one or more participants. The predetermined route may be provided by a race organizer, for example, as would be the case for a competitive running race like the New York City Marathon. In some embodiments, the predetermined route may comprise a route created and scheduled by the participant. For example, the predetermined route may be created and scheduled according to embodiments described in U.S. Publication No. 2011/0082641, entitled “Methods and Computer Program Products for Providing Information About a User During a Physical Activity.” In one embodiment, the predetermined route may be created and scheduled, for example, to be a 5 K race that takes place every Wednesday at the same location and time, and may be saved in the user's account on server 112. The server 112 may store information related to the fitness activity, including the predetermined route of the fitness activity, which may be downloaded to the portable fitness monitoring device 102 and the spectator device 202. In some embodiments, predetermined route information may be sent from server 112 and received by portable fitness monitoring device 102 in real-time. In some embodiments, the fitness activity may comprise a vehicle race, such as, for example, a car or boat race.

In an embodiment, the network 110 may be the internet. The internet is a worldwide collection of servers, routers, switches and transmission lines that employ the Internet Protocol (TCP/IP) to communicate data. In an alternate embodiment, the network may be a private network or intranet, such as, for example, a network dedicated to a particular fitness activity (e.g., the New York City Marathon). Other suitable communication networks may be used.

As will be appreciated by one of ordinary skill in the art, one or both of the portable fitness monitoring device 102 and the spectator device 202 may be a device such as, for example, a mobile phone, a smartphone, a dedicated fitness monitoring device, a sports watch, a personal digital assistant, a music file player (e.g. and MP3 player), a tablet computer, a laptop computer, an intelligent article for wearing (e.g. a fitness monitoring garment, wrist band, or watch), a dongle (e.g. a small hardware device that is capable of physically coupling to a first electronic device and/or wirelessly coupling to additional electronic devices), or any other suitable device dedicated or non-dedicated to providing the monitoring methods described herein. In one embodiment, the devices may be mounted to the body of the participant 100 or spectator 200. For example, the devices may be arm-mounted, chest-mounted, leg-mounted, or foot-mounted. In one embodiment, portable fitness monitoring device 102 and/or the spectator device 202 may be hand held.

In one embodiment, one or both of the portable fitness monitoring device 102 and the spectator device 202 comprise a global positioning system (GPS) equipped device. As shown, for example, in FIG. 2, the system 10 may include GPS satellites 20 that continuously emit GPS signals 22 which may allow the portable fitness monitoring device 102 and/or the spectator device 202 to continuously determine its position, velocity, and bearing according to known techniques. As will be appreciated, the fitness monitoring device 102 and the spectator device 202 may include the necessary GPS receiver/transmitter to receive and transmit location information. The portable fitness monitoring device 102 and the spectator device 202 may continuously transmit their location to the server 112 or the other respective device, or may transmit at a predetermined interval for power saving purposes. In one embodiment, the portable fitness monitoring device 102 and the spectator device 202 may only transmit location information after predetermined criteria have been met. For example, the location transmission may be based on one or more alert parameter, as described below.

The portable fitness device 102 may also be adapted to measure or receive data regarding various performance parameters associated with the participant's performance during the fitness activity. As shown in FIG. 2, in one embodiment the system 10 may include one or more additional sensors 104 and 106 for measuring performance parameters of the participant 100. For example, the system 10 may include a heart rate sensor 104 for determining heart rate information during the fitness activity, and an accelerometer 106. In one embodiment, the accelerometer 106 may be used in conjunction with a GPS-enabled portable fitness monitoring device 102 to determine the location of the participant 100 according to known techniques. For example, data provided by the accelerometer 106 may be used to provide a “dead reckoning” of the participant's location when the GPS signal is interrupted (e.g., due to the participant traversing the route under a bridge). The system 10 may include other sensors including, but not be limited to, a pedometer, pulsimeter, breath rate sensor, gyroscope, magnetometer, hydration sensor, thermometers, or other suitable sensors for detecting information that may be used to measure and/or calculate performance parameters. Each of the sensors of the system 10 may be in communication with the portable fitness monitoring device 102 and may provide performance data regarding the participant 100 during the fitness activity. The sensors may be in wired or wireless communication. In one embodiment, the performance data may be transmitted from the portable fitness monitoring device 102 to the server 112 and/or the spectator device 202 over the network 110. In some embodiments the performance data is stored on the portable fitness monitoring device 102.

In some embodiments, devices such as a race mat placed along a predetermined route of the fitness activity may be used in conjunction with a GPS-enabled portable fitness monitoring device 102 to determine the location of the participant 100. For example, many organized races (e.g., New York City marathon) have a plurality of race mats disposed at predetermined distances along the predetermined route of the race. The race mats may be adapted to transmit time-stamped location data that may be received by the portable fitness monitoring device 102, for example. This data may be used in conjunction with GPS data to determine the location of the participant 100.

Alerts regarding the location of the participant 100 and spectator 200 may be sent to the individuals based on one or more predetermined alert parameters. These parameters may be set by the participant 100 and/or the spectator 200 prior to or during the fitness activity. For example, in embodiments that include a “Live Tracking” application, the application may provide an interface for defining the alert parameters. The alert parameters may be stored on the server 112 and accessed by the portable fitness monitoring device 102 and/or spectator device 202 over the network 110 (e.g., when a monitoring application is initiated), or may be stored on the devices themselves.

In one embodiment, the alert parameter may be distance based. For example, the participant 100 and/or spectator 200 may be alerted when the other is within a predetermined distance of their present location (e.g., 200 m). In one embodiment, the parameter may be time based and the participant 100 and/or spectator 200 may be alerted when the other is within a predetermined time of their present location. In one embodiment, this determination (i.e., estimated time of arrival) may be made based on the current location of the participant 100 and performance data received by the portable fitness monitoring device 102 from one or more receivers or sensors. For example, the estimated time of arrival may be based on the current pace of the participant 100, as determined by the GPS functionality of the portable fitness monitoring device 102 and/or the accelerometer 106, for example. In other embodiments, the estimated time of arrival may be based on the current location of the participant, a predetermined speed, and/or a predetermined pace of the participant.

In one embodiment, the location alert parameter may be based on other participant performance data received by the portable fitness monitoring device 102 from one or more receivers or sensors. For example, the parameter may be based on the measured heart rate of the participant 100. When the heart rate of the participant exceeds a predetermined value, this may be indicative that the participant is undergoing a difficult portion along the route of the fitness activity, for example. At this point, an alert may be sent to the participant 100 that the spectator 200 is only 2 miles away, thereby encouraging the participant to endure this portion of the route. Alerts to the participant 100 and/or the spectator 200 may be based on other performance data in combination with, or, alternatively, not in combination with, the current location of the participant 100 and/or the spectator 200.

The alerts provided to the participant 100 and/or the spectator 202 may be visual, audible, tactile, or any combination thereof. To provide these alerts, the portable fitness monitoring device 102 and the spectator device 202 are adapted to convey information to the user in this manner. With reference to FIGS. 3 and 4, in one embodiment the portable fitness monitoring device 102 and the spectator device 202 include a display 103, 203 and a speaker 105, 205, respectively. To provide a tactile alert, the devices may include a vibrating element (not shown), for example, or other suitable tactile element.

A visual alert may visually indicate to the participant 100 and/or spectator 200 the other's location, as shown, for example, in FIGS. 3, 4, and 5. In one embodiment, the visual alert may include information about the fitness activity, such as, a map of the route of the fitness activity and may include one or more graphical symbols. The graphical symbols may provide specific location information and may provide an indication of the relative location between the participant and the spectator. In one embodiment, graphical symbols indicate the location of the participant 100 and the spectator 200 along the route. In one embodiment, for example, the visual alert may provide a precise location of where the spectator 200 is standing. In this manner, in some embodiments, the visual alert may include a detailed map (e.g., a Google satellite map) of the predetermined route of the fitness activity and the spectator's location superimposed on the map.

As the participant 100 continues to traverse the route, the graphical symbol may move accordingly in real-time on the display. In one embodiment, the depiction of the participant 100 and the spectator 200 may comprise a photo, avatar, or other symbol representative of the individual. The visual alert may include graphical symbols of landmarks along the course, such as, start line, finish line, mile markers, water stations, or streets and landmarks specific to a particular event (e.g., First Avenue and Lexington during the New York City Marathon). The graphical symbols, including photos and avatars, may be stored on server 112, fitness database 113, and/or social network database 114, for example. As shown in FIGS. 3 and 4, the visual alert may include text indicating that the participant 100 (or spectator 200) is approaching. For example, the text may indicate that “The spectator is approaching in 30 seconds,” “The spectator is at mile marker 20,” “The participant is approaching in 200 m,” “The spectator is located on the east side of the race course at First Avenue and Lexington,” or “The participant just crossed the finish line.” In one embodiment, the visual alert may include one or more advertisements related to the fitness activity or the location of the participant 100 or spectator 200, for example.

An audible alert may audibly indicate to the participant 100 and/or spectator 200 that the other is approaching through device speaker 105, 205 or headphones (not shown), for example. In one embodiment, the audible alert may include a standard message that “The spectator is at mile marker 20” or “The participant is approaching in 30 seconds.” In one embodiment, the audible alert may be a customized, pre-recorded message. For example, spectator 200 may pre-record a message such as “Keep it up John! I'll see you in one mile!” which may provide additional motivation and encouragement to the participant. Alerts may be stored on the respective devices 102, 202 or on server 112.

A tactile alert may also indicate to the participant 100 and/or spectator 200 that the other is approaching. For example, a vibrating element of the spectator device 202 may vibrate when the participant 100 is within 200 m or within a specific time, e.g., 20 seconds.

In one embodiment, visual, audible, and/or tactile alerts may be sent to the participant 100 and/or spectator 200 at predetermined intervals, locations, distances, or times that are unrelated to the location of the other. For example, an audible message may be sent to the participant 100 every 5 miles or 30 minutes of a race or when the participant or spectator arrives at a particular mile marker or landmark, for example.

In one embodiment, a participant 100 may receive alerts regarding other participants in the fitness activity. For example, the participant 100 may receive an alert that “You are one mile ahead of John,” or “John just finished the race.” In one embodiment, a spectator 200 may receive alerts regarding multiple participants 100, and the locations of multiple participants 100 may appear on a map at the spectator device 202.

In one embodiment, one or both of the participant 100 and spectator 200 may be registered to utilize the location and fitness monitoring methods described herein. In one embodiment, as shown in FIG. 6, for example, the participant 100 and/or spectator 200 may access a registration interface 300 (e.g., a website) on server 112 and provide registration information to server 112 from portable fitness monitoring device 102 and spectator device 202, respectively, or from another remote computing device 302. In embodiments that include a “Live Tracking” mobile application, the registration interface 300 may be provided as part of a smartphone application stored on the portable fitness monitoring device 102 or spectator device 202.

For example, a spectator 200 may be interested in tracking a participant 100 in real time during an upcoming fitness activity. In one embodiment, a spectator 200 may not be able to track the participant (e.g., receive location alerts during the fitness activity) without registering prior to the fitness activity. In one embodiment, the spectator 200 may access the registration interface 300 via the “Live Tracking” mobile application or website and provide registration information. The registration information may include information about the participant 100 that the spectator 200 wishes to track during the fitness activity. The participant information may include the participant's name, bib number, or other identifying information, for example. In one embodiment, the registration information may also include information about the spectator 200 that will allow the system 10 to communicate with the spectator during the fitness activity. The spectator information may include name, account information, email address, phone number, IP address, or other identification information. Other registration information, including, but not limited to, fitness activity information and payment information may be provided. In one embodiment, the registration interface 300 may be affiliated with the fitness activity. For example, the registration interface 300 may comprise the New York City Marathon website.

In one embodiment, participant 100 may invite one or more spectators 200 to track him or her during a fitness activity. In one embodiment, participant 100 may invite all or some members of a social network (e.g., Facebook®, LinkedIn®, Twitter®, etc.) to which participant may belong. For example, the participant 100 may send an invitation to his Facebook® friends, LinkedIn® contacts, or Twitter® followers to track him during an upcoming race. In one embodiment, the social network may comprise an athlete community associated with the participant's account on fitness database 113. In one embodiment, the spectators 200 may receive the invitation via their social network account on social network database 114. In embodiments that include a “Live Tracking” mobile application, an invitation indicator may be provided on the icon of the application, for example, indicating that the individual has an invitation to track a participant during a fitness activity. In other embodiments, spectators 200 may receive the invitation via email, text message, instant message, telephone call, or other suitable communication means. The spectator 200 may then accept the invitation. In some embodiments, the spectator 200 may track the participant 100 only after accepting the invitation. The acceptance may include spectator identification information that will allow the system 10 to communicate with the spectator during the fitness activity. In some embodiments, after accepting an invitation, the spectator may be required to register for tracking the participant during the fitness activity. In some embodiments, after registering or accepting an invitation, a participant or spectator may be required to download the mobile application from the server 112.

After the participant and/or spectator has registered and/or accepted an invitation, the system 10 may provide reminders to the user of the upcoming fitness activity. The reminder may be an indicator provided via the “Live Tracking” mobile application, or may be a message sent via other means, such as, for example, email, phone call, text message, instant messaging, and the like. The reminders may be provided at predetermined intervals such that the user may have a “countdown” to the upcoming fitness activity.

In one embodiment, the number of spectators 200 tracking the participant 100 during the fitness activity may be communicated to the participant. This spectator information may be based on the number of individuals who registered for tracking or accepted participant invitations, for example. The spectator information may be provided to the portable fitness monitoring device 102 audibly or visually before, during, or after the fitness activity. For example, before the fitness activity, participant 100 may receive a message at the portable fitness monitoring device 102 that “There are ten spectators registered to track you during the Race.” During the fitness activity, participant 100 may receive an alert at the portable fitness monitoring device 102 that “There are twelve spectators watching you.” along with a visual display of the location of each of the spectators. After the fitness activity, participant 100 may receive an alert that “Twenty spectators followed you during the Race.” Spectator information for each participant 100 may be stored in the individual's account on the fitness database 113 for review and comparison. For example, members of an athlete community associated with fitness database 113 may compete to be the individual with the most fitness activity spectators or “followers.”

In one embodiment, participant 100 may activate the live tracking feature to allow location information related to the participant 100 to be accessed by spectator 200 during the fitness activity. In one embodiment, activation may be conducted manually. For example, in one embodiment, participant 100 activates the tracking feature via the “Live Tracking” mobile application stored on the portable fitness monitoring device 102. In another embodiment, participant 100 activates the tracking feature via a website. In another embodiment, activation may occur automatically. For example, the live tracking feature may be automatically activated when the participant 100 is within a predetermined distance from the starting line of the fitness activity or on the race course. In one embodiment, participant 100 may receive visual or audible feedback that the live tracking feature is activated. In some embodiments, spectator 200 may also be required to activate the live tracking feature to allow location information related to the spectator 200 to be accessed by the participant 100 during the fitness activity. Activation of the live tracking feature may address privacy concerns.

After the live tracking feature has been activated, the system 10 may begin to record performance data from one or more sensors and receivers and may transmit participant location information. In one embodiment, the system 10 may only record and/or transmit data during the fitness activity. For example, if a particular race occurs on June 7 at 10 AM, the system 10 will begin recording and/or transmitting data at this time. In one embodiment, the system 10 may continue recording and/or transmitting for a predetermined amount of time, for example, based on an estimated time of completion by participant 100 (e.g., between 10 AM and 12:15 PM). The estimated time of completion may be provided as input by the participant prior to the fitness activity or may be based on historical data related to the participant or the fitness activity. In another embodiment, the participant 100 may manually stop the recording and/or transmitting at the completion of the fitness activity. In one embodiment, the recording of data may be provided as described in U.S. Publication No. 2011/0082641, entitled “Methods and Computer Program Products for Providing Information About a User During a Physical Activity,” the disclosure of which is incorporated in its entirety by reference thereto.

In one embodiment, the system 10 may transmit the location of the participant 100 and/or record participant performance data based on predetermined parameters. For example, with reference to FIG. 7, the system 10 may only transmit the location of the participant when he is within a predetermined transmission/recording area 402 of the route 400 of the fitness activity. In one embodiment, the system 10 will not transmit participant location information in the area 404 outside of the transmission/recording area 402. The system may also not record participant performance data in the area 404. In this manner, participants may be prevented from cheating during the fitness activity by taking a shorter or less challenging route outside the predetermined route 400. In addition, the privacy of the participant may be maintained by restricting the transmission/recording area 402. Similar restricted transmission areas may be applied to the spectator device 202.
